Display device, displaying method and computer-readable storage medium

Abstract

A display device includes an identification information receive unit that receives, from a communication device which transmits a radio signal to a predetermined range, predetermined identification information of the communication device, an electromagnetic wave range receive unit that receives an electromagnetic wave range of the communication device based on electromagnetic wave range parameters corresponding to the identification information received by the identification information receive unit, and a screen generate unit that generates a screen for displaying the electromagnetic wave range received by the electromagnetic wave range receive unit at a predetermined position of a predetermined map.

What is claimed is: 
     
         1 . A display device, comprising:
 an identification information receive unit configured to receive, from a communication device which transmits a radio signal to a predetermined range, predetermined identification information of the communication device;   an electromagnetic wave range receive unit configured to receive an electromagnetic wave range of the communication device based on electromagnetic wave range parameters corresponding to the identification information received by the identification information receive unit; and   a screen generate unit configured to generate a screen for displaying the electromagnetic wave range received by the electromagnetic wave range receive unit at a predetermined position of a predetermined map.   
     
     
         2 . The display device according to  claim 1 , further comprising a storage unit configured to store image data of the electromagnetic wave range,
 wherein the screen generate unit is configured to generate the screen for displaying the electromagnetic wave range at the predetermined position of the predetermined map by using the image data from the storage unit.   
     
     
         3 . The display device according to  claim 1 , wherein the electromagnetic wave range receive unit is configured to receive the electromagnetic wave range based on a relationship between an installation height of the communication device from a ground or a floor and a transmission output of the communication device which are included in the electromagnetic wave range parameters. 
     
     
         4 . The display device according to  claim 1 , wherein the screen generate unit is configured to change a scale of the electromagnetic wave range based on a scale of the predetermined map and generate the screen for displaying image data corresponding to the scale-changed electromagnetic wave range at the predetermined position of the predetermined map. 
     
     
         5 . The display device according to  claim 1 , wherein the radio signal transmitted by the communication device carries position information of the communication device. 
     
     
         6 . A displaying method performed by a display device, comprising:
 receiving by an identification information receive unit of the display device, from a communication device which transmits a radio signal to a predetermined range, predetermined identification information of the communication device;   receiving by an electromagnetic wave range receive unit of the display device an electromagnetic wave range of the communication device based on electromagnetic wave range parameters corresponding to the received identification information; and   generating by a screen generate unit of the display device a screen for displaying the received electromagnetic wave range at a predetermined position of a predetermined map.   
     
     
         7 . A non-transitory computer-readable storage medium storing a program representing a sequence of instructions, the program which when executed by a computer included in a display device, causes the computer to perform a displaying method comprising:
 receiving by an identification information receive unit of the display device, from a communication device which transmits a radio signal to a predetermined range, predetermined identification information of the communication device;   receiving by an electromagnetic wave range receive unit of the display device an electromagnetic wave range of the communication device based on electromagnetic wave range parameters corresponding to the received identification information; and   generating by a screen generate unit of the display device a screen for displaying the received electromagnetic wave range at a predetermined position of a predetermined map.
